You can also get replacement cores from Eureka...wing-k

I've only done foam core wings once, for a Big John bipe, but it worked so well I'll do it again. I bought cores from Eureka and watched a couple of Youtube videos. The one I went with used Gorilla glue. What was interesting was to see how little he used. He rolled it out with a firm four inch paint roller. At first I though it would never work, but as I kept rolling it spread out. Then I misted the balsa sheets and applied weight. I used a piece of marble, as above, with some slate stacked on top. It worked great. For anyone who used vacuum bagging, more power to ya, but I don't see how it could end up any lighter than what I got with weights. Also the tip above was good...don't edge glue the sheets. I did, but won't bother the next time.

RCG seems to have changed photo uploading method and after getting everything set up I couldn't figure out where to click to make them attach...sorry. Jim
